When cars are changing direction they are also changing what?
When cars are changing direction, they are also changing their velocity vector, which includes speed and direction. This change in velocity requires acceleration, which can be in the form of turning left or right, slowing down, or speeding up.
Can a body have zero velocity and still be accelerating?
Yes, a body can have zero velocity and still be accelerating if its speed is changing, either increasing or decreasing, over time. This is because acceleration is a measure of how the velocity of an object is changing, regardless of its current velocity.
How do you measure instantaneous velocity?
You can transform linear velocity into rotational velocity with a rolling wheel. Rotational velocity can be measured inside a gravity field because of generated centrifugal force. When you suspend your arms freely while rotating, the angle between your body and your arm is a measure for the rotational speed.
What are the three measure related to the study of motion?
distance, speed, and time
What does constant velocity or acceleration mean?
"Constant" means that regardless of when you measure it, the result is always the same. "Velocity" means speed and its direction. "Acceleration" means the rate at which speed is changing, and the direction in which it's changing.
Why do you had to calculate acceleration with velocity?
Because acceleration is the rate of change of velocity: it is a measure of how quickly velocity is changing.

What does a tangent to a velocity-time graph measure?
It will measure acceleration in the direction towards or away from the origin.

What is velocity and how is it calculated as the distance traveled over a specific period of time?
Velocity is a measure of how fast an object is moving in a specific direction. It is calculated by dividing the distance traveled by the time it took to travel that distance. The formula for velocity is velocity distance/time.
How are position and velocity related?
Position is the location of an object in space, while velocity is the rate of change of that position over time. Velocity is the derivative of position with respect to time, meaning that it is a measure of how fast the position of an object is changing.
What is needed to measure velocity of an object?
To measure the velocity of an object, you need its change in position over a specific time interval. This is typically calculated by dividing the change in position by the time it took to move that distance. You can use tools such as radar guns, speedometers, or motion detectors to measure the velocity of an object.
What is the measure of an object's mass and velocity called?
The measure of an object's mass is called mass, and the measure of its velocity is called velocity.
What is the rate at which velocity change called?
The rate at which velocity changes is called acceleration. Acceleration is the measure of how quickly an object's velocity is changing, either increasing or decreasing. It is a vector quantity, meaning it has both magnitude and direction.
